: I have been withdrawing from 5 mgs of methadone (for overe 25 years) for the last 20 days. However, I did have percocet to help for a while because I had been prescribed the pain killer for recent lung surgery. (I HAVE lung cancer). Now, my surgical doctor won't refill the scrip and my primary doctor has reservations about it. I've already know how to withdraw from the percocet (if necessary) and what I can get from health food store). I don't know how to get some percocet for the withdrawal and ability to sleep at night.
